X-ray Talbot capturing apparatus

There is provided an X-ray Talbot capturing apparatus that emits X-rays in a cone beam shape from an X-ray generator, capable of producing gratings as easily as possible and of minimizing a production cost. An X-ray Talbot capturing apparatus 1 includes a G1 grating that is a phase grating, a G2 grating that is an absorption grating, a X-ray generator 11 that emits the X-rays, and an X-ray detector that includes a plurality of two-dimensionally arrayed conversion elements and captures a moire image Mo formed on the G2 grating. The G2 grating is located at a position where a self-image of the G1 grating 14 is formed, and both of the G1 grating and the G2 grating are in a plane shape. Slits of the G1 grating are formed to be perpendicular to a surface direction of a substrate on which the grating is formed, whereas slits of the G2 grating are formed to be parallel with the X-rays emitted in the cone beam shape from a focus F of the X-ray generator.
